To all zrmm, it may concern: the drawings, to insure the issuing of the acid lle it known that I, GUSTAVUS W'. OOON, a iu smooth compact streams oi' currents. In citizen oftheUnited States, residingatlVashsome constructions of chemical tire-extinington, in the District of Oolu m bia, have inguishers the acid has been brought suddenly 55 vented certain new and useful Improvements into and instantly coininingled with the al kain Fire-Extinguishers; and I do hereby deline water, and the sudden generation of a clare the following to be a full, clear, and eX- large amount of gas often results in the burstact description of the invention, such as will ing of the tank.

The upper end of the acid-holder shape, as shown, and the rod D is provided is provided with a cap O, and this cap is prowith a pin d', resting upon the upper end of vided with one or more openings c. These the sleeve.l The upper end ofthe rod D is roo 5o openings are for the discharge of the acid and provided with a handle D2, by which the rod are preferably made tapering, as shown in can be turnedin either direction. Such turning of the rod causes the pin d to engage with the cam-surface ofthe upper end of the sleeve, which raises the rod and com presses the spring d, releasing the acid-holder, permitting it to turn upon its pivotal supports, and assume an inverted position, as shown in Fig. 2, in which position the acid contained is discharged into the Water in the outer tank.

If the acid-holder were inverted in a closed tank of Water, the gas-generator would soon develop such a pressure upon the water as to seriously retard the outward flow ot' the acid from the holder. To avoid this is one of the objects of my present construction.

The acid-holder is never entirely full, and during the movement of inverting its position a part of the air within the holder escapes, admitting a small amount of water to the interior ot the holder, generating gas therein, which rises to the upper end of the holder when it reaches its inverted position, creating a pressure upon the acid in the holder and forcing the acid out through the openings c. As soon as the pressure in the tank exceeds the pressure within the holder the flow of acid from the holder is checked; but this excess of pressure outside the holder will force Water upward in the tube c2 upon the top of the acid Within the holder, thereby generating and an increase of pressure therein, which will cause the acid to be again forced outwardly through the openings c. 'lhe openings c being of small size, the streams of acid become commingled with the Water before reaching the bottom, so that no acid is ever forced out of the tank, While the small size of the streams and the retarding eiect of an excess of pressure in the tank secure such a gradually-progressive increase of pressure that all danger of an explosion is avoided.

What I claim, and desire to secure by Letters Patent, is Y l. In a chemical {ire-extinguisher, the com bination with the tank for holding alkaline material, of the acid-holder having 'one or more discharge-openings of small size and means for introducing alkaline material into said acid-holder to generate gas therein, substantially as described.

2. In a chemical re-extinguisher, the combination with the tank for containing an alkaline solution, of an acid-holder having an acid-discharge opening oropenings and means other than the said discharge-opening for introducing material into the acid-holder to generate gas therein, substantially as described.

3. In a chemical fire-extinguisher the combination with the tank for holding an alkaline solution, of an acid-holder therein having an acid-discharge opening or openings means for closing and opening said dischargeopenings and means other than the said discharge-openings for introducing a liquid into said holder to generate gas therein, substantially as described.

4. In. a chemical {ire-extinguisher, the combination with a tank for holding an alkaline solution, of an acid-holder having dischargeopenings, of means other than the dischargeopenings for introducing material into said acid-holder above the acid to generate gas therein, substantially as described.

5. In achemical fire-extinguisher the combination with the tank for holding the alkaline solution, of the acid-holder having openings in one end of the same, said holder having a tube extending from one of the said openings to near the closed end ol' the holder and means for depressing the open end of the holder below the surface of the said solution, whereby the pressure engendered in the tank is caused to force the solution into the holder, substantially as described.

6. In a chemical tire-extinguisher the combination with the tank for holding the alkaline solution, of the acid-holder having openings in one end and the tube extending to near its opposite end, said holder being pivoted intermediate its ends, means for holding the open end of the holder above the said solution and means for inverting it to bring said opening beneath the solution, substantially as described.

7. In a chemical lire-extinguisher the combination With the tank for holding the alkaline solution, of the acid-holder having openings in one end and the tube extending to near the closed end'ot' the holder, said holder being eccentrically pivoted, means for holding the holder with the end provided with openings uppermost and releasing means, substantially as described.

8. In a chemical fire-extinguisher, the combination with the tank for holding the alkaline solution, of the acid-holder located therein having openings in one end and a tube within said holder extending from one of said openings to near the opposite end ofthe same, means for closing the openings in the acidholder and means for removing the closure and bringing the acid-holder into operative relation With the alkaline solution, substantially as described.
